What is the primary focus of macroeconomics?

The primary focus of macroeconomics is the study of the economy as a whole. This branch of economics examines broad issues such as overall economic growth, the total level of employment, inflation, and the dynamics of national income. Macroeconomics seeks to understand how different sectors of the economy interact and how policy decisions can impact these interactions on a large scale.

In contrast, the other options are more narrowly focused. For instance, studying individual markets pertains to microeconomics, as it analyzes supply and demand, pricing, and consumer choices within specific sectors. Analyzing company performance is also a microeconomic concern, emphasizing firm-level data rather than considering the larger economic picture. Similarly, the examination of consumer behavior delves into how individuals make purchasing decisions and allocate resources, which again falls under the microeconomic domain. Therefore, the correct answer reflects the overarching theme of macroeconomics, which aims to provide insights into the functionality and performance of a national or global economy.
